Mayor launches `hyperlocal` air mapping in London with smart sensors and Google Street View cars
On 15 January the Mayor of London, Sadiq Khan, launched the world's most advanced and comprehensive network of air quality monitors. David Carruthers represented CERC at the launch.
Breathe London is a consortium led by the Environmental Defense Fund, including CERC, Air Monitors, University of Cambridge, National Physical Laboratory and Google Earth Outreach, who have equipped two of their iconic Street View cars with air quality sensors. These will take pollution readings approximately every 30 metres at tens of thousands of locations whilst they travel through London's streets, building up a picture of London's air quality over the course of a year and identifying areas of poor air quality that the network of fixed monitors might miss. Meanwhile, 100 state-of-the-art fixed sensor pods will be mounted on lampposts and buildings close to known air quality hotspots and sensitive locations such as schools and nurseries.
The data these monitors collect from across the capital will provide an unprecedented level of detail about London's air quality and deliver new insight into the sources of pollution. CERC's renowned ADMS-Urban model will be used together with the sensor data to generate hyper-local air quality mapping both for nowcasts and forecasts, and for policy studies. The data generated by this new network will be available for the public to view on an interactive online map built by CERC on the Breathe London website. The map will show Londoners the condition of the air they are currently breathing.
